We're currently working on some bigger new features for pixpet so stay tuned. :P
Nevertheless two smaller changes have been made today:

Event Badges

A new badge category has been added: Event Badges. This category is meant for badges concerning all kinds of site events. This category has no "badge count" like the others since they are now unobtainable for new users. Following badges are currently listed as Event Badges: Crack The Egg Code and Early Adopter.

Cook Ingredients Search

It is now possible to search for ingredients in the cooking section which should make adding ingredients more smooth!
